Is there a binary of libobjc2 in existence for windows??

About to pull my hair out here.  As usual, trying to get one thing working 
using open sourced has pushed me 50 stack levels down of trying to compile 
dependencies.

I'm assuming I can't use arc + clang without linking against libobjc2 on 
windows, so I've been trying to get it installed.

Orignal problem:

$ make CC=clang
This is gnustep-make 2.6.2. Type 'make print-gnustep-make-help' for help.
